The appropriate connection to the RS485-USB depends on the type of serial

network: RS422, 2-wire RS485 or 4-wire RS485. The following figure shows a

description of all RS485-USB connection terminals.

A shielded twisted-pairs cable is recommended for wiring the communication

bus from the converter to all network devices. The shield should be grounded and/or

connected to the common terminals of all devices. The minimum recommended wire

gauge is 24 AWG (0.2 mm
